JOHN M. BEADLES, OF DENVER, COLORADO.

LAMP-BURNER.

Application filed .T une 17,

fo all whom it may concern.'

Be it known that I, JOHN M. BEADLEs, a citizen of the United States ofAmerica, residing at Denver, in the county of Denver and State ofColorado, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a specification.

My invention relates to certain new and useful improvements in burnersfor oil lamps and its object is to provide a device which by closing orclogging the passage in the wick tube when the wick contained thereinhas been lowered beneath its orifice, will automatically extinguish theiiame, hinder the emission of smoke from the charred end of the wick andprevent evaporation of the oil or other inflammable liquid contained inthe light producing vessel of which the burner forms part. I attainthese objects by the means illustrated in the accompanying drawings inthe various views of which like parts are similarly designated and inwhich Figure l-represents a plan view of my improved lamp burner withits crowning portion removed. Fig. 2-a vertical section taken along aline 2 2, Fig. 1, Fig. B-an enlarged vertical section of the upperportion of the wick tube with the wick in position to be ignited. Fig.4-a similar view with the wick lowered and the passage in the tube aboveit, closed, Fig. 5-an enlarged horizontal section taken along a line5-5, Fig. 2, Fig. 6, a horizontal section through the wick tube of aburner having a circular wick, and Fig. 7, a section taken along a line7 7, Fig. 6.

Referring to the drawings, let the reference numeral 2 designate a lampburner including the stopper 3 which in practice is secured within theorice of the lamp 4, the thereupon supported perforated, horizontalshield 5 with the crowning portion 6 by which the current of air isdeflected upon the wick, and the vertical wick tube 7 which extendingthrough the stopper 3 and the shield 5, contains the wick 8 by means ofwhich the inflammable 'fluid contained in the lamp, is drawn up to beburned at its upper end when exposed above the orifice of the tube.

The burner is provided with the usual devices for adjusting the wick,such as a star wheel 9 which in engagement with the side ofSpecification of Letters Patent.

the Wick may be rotated by manipulation of a knob l() at the end of aconnecting spindle 11. In proximity to the upper end or orifice of thewick tube 7, is a recess 12 formed by a laterally projecting,protuberant portion or bulge 13 of one of its sides and which eX-tending horizontally along the full width thereof, houses a preferablycylindrical weight 14 which in longitudinal dimension equals theinternal length of the tube while its diameter slightly eXceeds thewidth thereof. The lower surface of the recess slopes from its rearmostportion towards the tube so as to form an inclined. plane 15 along whichthe weight 14 may slide'or roll into the tube and upon the wick when thelatter is lowered beneath the passage 12a which connects the interior ofthe tube with the recess.

When the up er end of the wick 8 extends beyond the ori ce of the tube7, in readiness to be ignited, its portion occupying the tube retainsthe weight 14 within the recess until, to' extinguish the flame, thewick is lowered by rotation of the wheel 9, when as soon as its upperend has reached the lower edge of the mouth of the recess 12 and inconsequence is moved out of engagement with the weight, the latter,impelled by gravity, will pass along the inclined lower surface of therecess into the tube and upon the upper edge of the wick. The naturalresult is that the flame produced by the burning oil will be eX-tinguished by exclusion of the oxygen and will be clogged so as toprevent the emission of smoke and evaporation of the liquid contained inthe lamp. Subsequent raising of the wick will cause the weight towithdraw into the recess until it has regained its normal position inengagement with the side of the wick.

In burners constructed with a cylindrical the weight employed toobstruct the interior chamber between the concentric tubes 18 and 18',which compose the housing, is divided into a plurality of circularlyarranged sections 19 which normally occupy an annular recess 20 producedby a surrounding bulge on the outer tube and which are adapted tocollectively close the passage between the tubes when by lowering of thewick they are allowed to move thereinto.
